Tetrathiafulvalene station

In heterocircuit [2]catenane 174+, the tetracationic cyclophane initially encircles the more electron-rich tetrathiafulvalene station (TTF) as evidenced... 

Conductivity differences were seen in a bistable [3]catenane closed-loop molecule, with a naphthalene group as one station, and tetrathiafulvalene as the second station, decorated by a tetracationic catenane salt that could travel on the catenane, like a train between two stations, making a nano-switch [141]. 

More recently, the second-generation molecular shuttle 374+ (Fig. 13.32) was designed and constructed.38 The system is composed of two devices a bistable redox-driven molecular shuttle and a module for photoinduced charge separation. In the stable translational isomer, the electron-accepting cyclophane 124+, which is confined in the region of the dumbbell delimited by the two stoppers Tj and T2, encircles the better electron donor tetrathiafulvalene (TTF) station. 

The [2]rotaxanes, which contain tetrathiafulvalene (TTF) and 1,5-dioxynaphtha-lene (DNP) as the two recognition stations and cyclobis(paraquat-p-phenylene) (CBPQT4 + ) as the cyclic moiety, have been comprehensively investigated by Stoddart and coworkers.68 We have recently reported two new TTF-DNP-CBPQT4+ [2]rotaxanes 62 and 63. In these two [2]rotaxanes, the TTF moiety is the 4,4 (5 )-dialkylthiotetrathiafulvalene that is rather easily accessible based on the synthetic procedure developed by us previously,69 and two different spacers are used the cyclohexyl and alkyl chains. Two stopper units are the G2-dendritic moieties. 

Recently, Spruell et al. synthesized and characterized a single-station [2]catenane that exhibited fundamental differences from the bi- and multistation catenane switches that currently exist [91]. Tetrathiafulvalene (TTF) is a electrochemically...
